fix: Correct endDate inclusion by adding 1-day offset

[shfc]

I discovered that when the parameter until is set to endDate, the event is not generated on that specific date. So I made a 1-day adjustment to the date, and the event is now being generated as expected on both Firefox and Chrome.

I've investigated this bug further, and the cause is now clear. The issue arises when the course's start time exceeds the until time. For example, in the scenario shown below, the until time calculated by the original code doesn't cover the course's start time, so the event is not generated as expected.

After applying the fix, the until time is set to midnight after the endDate, ensuring that the last event occurrence is included, as shown in the image below.

Thanks for the test data, the issue is much clearer now. Missed this PR until the update just then, sorry for not reviewing earlier!

No worries! The original PR didn't fully address the root cause and still had potential issues. It's clearer now and easier to review.
